The GTM Engineer bridge.

Harmonic Security closed the $17.5M Series A in October 2024 and you are building the Clay stack inside a 48-person AI security company selling into regulated enterprise. The coverage you are owning solo, signal layer, routing, multi-buyer sequencing, is enough work for 2 people while the motion scales. I run alongside you for 30 days so the next layer ships now and you keep architectural ownership of everything I touch.

6 weeks $15,000 fixed For the GTM engineer solo on the Clay stack, a second pair of hands beats a second seat.

The bottleneck is bandwidth, not capability.

You know what the Clay stack needs next. You know which sequences are underperforming and which signals you wish you could weight differently. The constraint is that you cannot architect the next layer and maintain the current one with the same set of hours. I take the build work you have already scoped in your head, ship it inside your stack to your standards, and hand it back documented. You stay the GTM engineer of record. I am the second set of hands while you scale.

Three things only an internal builder can fix.

Roadmap longer than calendar

Every GTM engineer at this stage has a backlog of builds that would each move a metric. The question is not whether they are worth doing. The question is whose hours ship them this quarter.

Multi-buyer security deals demand more plumbing

CISO, IT, and legal across a regulated enterprise account is 3 sequences, 3 scoring weights, and per-stakeholder routing. That is real build time on top of maintaining the existing Clay stack.

Documentation debt grows silently

A solo GTME ships fast but the runbooks lag. When the next hire lands or you take a vacation, undocumented automation becomes a risk. Building alongside is the cheapest time to write the docs.

A 30-day sprint inside your stack, built to your standards, handed back documented.

  1. Weeks 1 to 2

    Co-scope against your existing roadmap

    Pick the 2 to 3 builds you would ship next if you had the hours. Likely candidates: multi-source enrichment for regulated buyers, persona-level routing for security deals, scoring weights tuned for high-fidelity signal scarcity. You set the architecture, I do the build.

  2. Weeks 3 to 4

    Ship inside your stack and document the handoff

    Built in your Clay environment using your conventions. Runbooks written as we go. You keep architectural ownership and the docs your future hire reads on day one. Same delivery model I used at AssetWatch in 4 weeks (built the system, wrote the maintenance guide, Tyler's team owns the run).

Salesforce in plain English, shipped in 4 weeks.

AssetWatch leadership wanted natural-language access to pipeline, accounts, demo outcomes, and work orders without filing a RevOps ticket for every question. I shipped a custom GPT in ChatGPT Enterprise that translates English to SOQL and queries production Salesforce live. Two Knowledge files made it work: an auto-generated schema catalog covering 26 objects and 3,800+ fields, plus a hand-curated semantic layer encoding AssetWatch tribal knowledge, so "who owns this deal" returns the Solution Architect and "deal size" returns ARR, not the raw admin fields. Read-only, leadership-facing, 4 weeks. Tyler's team owns the maintenance now.

Same play I would run for Harmonic Security. Different stack, same fixed-fee discipline.

$15,000, fixed. 6 weeks. One invoice.

  • Signal architecture
  • Account list and buying-committee map
  • Sequence build, live send, and deliverability infrastructure

Documentation and handoff included, not billed. If volume justifies it after the bridge, $25,000 / 90-day retainer extends the system. Your call, not mine.

Send me a sentence on how the pipeline reads today, and I will reply within a day with a 1-page scope and an honest read on whether this fits.
